Research on hierarchical Linkage threat response Model of Power Information Network

Nowadays,a lot of work has been done on network security protection. Only by fully identifying security risks can effective security measures be taken. However, a large number of continuous operation of security protection equipment produces a huge amount of alarm, which makes it difficult for security administrators to understand the security threat status of the system in the face of a large number of alarm information, and can not take appropriate response measures in a timely manner. can not integrate multi-dimensional security information, linkage of multi-type security equipment for threat defense means and measures. Therefore, by studying the threat response mechanism, this paper establishes a hierarchical linkage defense threat response model, and puts forward an intelligent decision-making method of linkage strategy on the basis of the threat response model to optimize the security policy.
